alt Hacker NewsThis reminds me that I just learned the other day that .a files are unix archives, which have a textual representation (and if all the bundled files are textual, there's no binary information in the bundle). I thought .a was just for static libraries for the longest time, and had no idea that it was actually an old archive format.
It may amuse you to learn that tar headers are designed as straight up text tables with fixed-width columns, marred only by the fact that modern implementations pad with 0s instead of spaces. The numbers are encoded as octal digits!
